Why is 248x248 the maximum bi dimensional array size I can declare?

Question

I have a program problem for which I would like to declare a 256x256 array in C. Unfortunately, I each time I try to even declare an array of that size (integers) and I run

Unless you're running a very old machine/compiler, there's no reason that should be too large. It seems to me the problem is elsewhere. Try the following code and tell me if it works:

#include 

int main()
{
  int ints[256][256], i, j;
  i = j = 0;
  while (i<256) {
    while (j<256) {
    ints[i][j] = i*j;
    j++;
   }
   i++;
   j = 0;
 } 
 printf("Made it :) \n");
 return 0;
}
